FAQ

LED bulb after the power failure, still glimmer, can last hours or even all day, what is the reason?!
The meter usually doesn't turn because the current is too small to drive the meter (Mechanical), of course, the electronic meter also depends on the sensitivity. I don't think so. At least I used to do LED (light power about 0.5W it) is equivalent to 3W incandescent lamp brightness around. The meter does not rotate when it is shining normally.
What are the driving IC used in LED bulb?
M8900 can replace BP3309, SY5810 SY5840 MT7930, ME 8316, without modifying the circuit used directly.M8900Is an original side feedback, with single stage active PFC high precision LED constant current control chip, M8900 integrated single level active PFC line, can achieve higher power factor and very low total harmonic distortion, chip canThe quasi resonant mode is achieved, thereby achieving higher efficiency and reducing switching losses. M8900 features multiple protection functions to ensure system reliability, including LED open circuit protection, chip overvoltage protection, and UVLO deficiencyVoltage protection, LED short circuit protection, cycle by cycle current limiting, etc..
How to identify Ic constant current LED bulb?
Hello, LED market is now very confused, this problem is the use of LED lamps of the users are more concerned about the problem, the so-called IC constant current drive power refers to the LED lamp (commonly known as the transformer) with a constant stream of multifunctional IC chip, the IC is generally 5-8 feet (depending on the model and decision scheme), role is to ensure that the current through LED lamp is controlled in a relatively constant parameter, ensure the long-term stability of LED lamp work at constant current. When the input or output voltage is changed, the current through LED remains constant, so the constant current IC of the LED light stability and service life is directly related to the IC also includes internal short circuit protection, overtemperature protection function of open protection etc.
LED bulb w can replace 40W incandescent lamp
The standard of luminous flux according to the luminaire is lumen (LM). Incandescent lamps are w 11-12lm per 40w=440-480lm
Can the bulb's true life reach 30000~50000 by LED?
According to the current LED manufacturing technology, LED bulb has a lifetime of up to 30000 hours.
LED bulb is broken. The luminous patch is not bad. Can it be made into USB lamp?
Cannot connect directly. LED bulb is usually a series of LED series, and then parallel, generally about 12V. Single chip LED generally rated voltage at 3.0V~3.6V, USB, output voltage of about 5.0V.
What's the reason why LED bulb gets a lot of heat?
If the radiator has a large radiating area, the temperature is low
Is it possible to manually weld LED bulb bulbs?
If you can guarantee that you can add thermal grease just fill the gap without obstructing the normal contact, it is useful, but this process is very difficult for you to do, and the theory can improve the thermal efficiency of thermal grease, but actually you are not up to the process it is possible to reduce the thermal efficiency, you added more is to seek psychological comfort, you can on the heating plate welding of light, with one side of the thermal grease solder, such thermal effect is better
